+
+# Scope {toc}
+
+## This Standard covers enclosed combination and manual motor starters that control and protect a single motor served by an individual branch circuit outside a motor control center. {note}
+
+## A combination starter assembles a disconnecting means, branch-circuit short-circuit and ground-fault protection, a contactor, and a motor-overload relay into one listed enclosure. A manual motor protector (MMP) provides the disconnect and short-circuit protection with manual overload reset but no contactor, suiting motors that need no remote start/stop. {note}
+
+## The Contractor shall furnish and install enclosed motor starters complete with disconnecting means, overcurrent protection, contactor, overload relay, control power, enclosure, and accessories as specified and as scheduled.
+
+## Each starter shall control one motor on one branch circuit unless the Contract Documents specifically indicate a grouped or multi-motor installation.
+
+## Grouped motor installations, lineups on a common bus, and centralized motor control belong to [[sync/motor-control-centers]] and are not furnished under this Standard. {note}
+
+## Variable-frequency drive packages with integral bypass and disconnect are specified under [[sync/low-voltage-variable-frequency-drives]] and are excluded here. {note}
+
+## Disconnect switches furnished without an overload relay or contactor assembly are specified under [[sync/enclosed-switches-and-disconnects]] and are excluded here. {note}
+
+## Medium-voltage starters above 600 V, electronic soft starters, and starters factory-wired inside packaged equipment are outside the scope of this Standard. {note}
+
+# Referenced Standards {toc}
+
+## Equipment, materials, and installation shall comply with the latest adopted edition of each of the following unless a specific edition is cited or a different edition is enforced by the Authority Having Jurisdiction.
+
+## Where referenced standards conflict, the more stringent requirement shall govern unless the Engineer of Record directs otherwise in writing.

+
+# Quality Assurance {toc}
+
+## Each combination motor controller assembly shall be listed and labeled to UL 508A as a factory-assembled industrial control panel, or shall be a field-assembled combination of individually listed UL 508 / UL 60947-4-1 components forming a listed combination.
+
+## Each contactor and overload relay shall be listed to UL 508 or UL 60947-4-1 as applicable to its frame type.
+
+## The manufacturer shall be a producer regularly engaged in the manufacture of motor control equipment of the type specified for a minimum of five years.
+
+## The installing Contractor shall employ electricians licensed in the jurisdiction of the Work and experienced in the installation of motor control equipment.
+
+## Mixing components from different manufacturers within one combination assembly is prohibited unless the resulting assembly carries a tested or calculated UL 508A series-combination SCCR rating that covers every component. {note}
+
+## One frame standard — NEMA or IEC — shall be designated for the entire project and held consistently across all starters to limit the spare-parts inventory and simplify maintenance.
+
+## The project frame standard shall be stated in the project electrical general requirements; ad-hoc mixing of NEMA and IEC frames across a project creates long-term maintenance and stocking problems. {note}
+
+```datasheet

+
+# Environmental and Service Conditions {toc}
+
+## Starters shall be rated for continuous operation in the ambient and exposure conditions at their installed location without derating below the connected motor load.
+
+## Standard starters are rated for a maximum ambient of 40°C; locations in direct sun, in unconditioned mechanical rooms, or otherwise exceeding 40°C (104°F) require a 50°C-rated device or an enclosure derate. {note}
+
+### Where the installed ambient exceeds 40°C, the Contractor shall furnish starters rated for 50°C ambient or shall apply the manufacturer's published derating.
+
+## Enclosure type shall be selected for the environment of the installed location in accordance with NEMA ICS 6.
+
+## NEMA 3R is raintight but is not corrosion-resistant; coastal salt air, chemical wash-down, and wastewater service require a NEMA 4X 316 stainless steel or fiberglass enclosure rather than NEMA 3R. {note}
+
+### Outdoor starters in corrosive, coastal, or wash-down environments shall be furnished in NEMA 4X enclosures of an explicitly specified corrosion-resistant material.
+
+```datasheet
+label: Enclosure Type

+
+# Starter Type and Configuration {toc}
+
+## The starter type shall match the control function required by the driven load, the available fault current, and the project frame standard.
+
+## A full-voltage non-reversing (FVNR) starter is the default configuration; full-voltage reversing (FVR) is furnished only where the driven load requires both directions of rotation. {note}
+
+## Combination starters are classified by their branch-circuit protective device: fusible-switch type (switch plus fuses), circuit-breaker type (thermal-magnetic breaker), and motor-circuit-protector (MCP) type (instantaneous-only breaker). {note}
+
+## The MCP type uses an instantaneous-only breaker and achieves the highest available SCCR — up to 100 kA at 480 V — making it the preferred type where available fault current is high. {note}
+
+## A manual motor protector (MMP) provides the disconnecting means and short-circuit protection with a manual-reset thermal-magnetic trip and no contactor, and is appropriate only for motors that require no remote start/stop. {note}
+
+```datasheet
+label: Control Configuration
+type: radio
+options:
+ - Full-voltage non-reversing (FVNR)
+ - Full-voltage reversing (FVR)
+ - Manual motor protector (MMP) only
+default: Full-voltage non-reversing (FVNR)
+```
+
+```datasheet
+label: Combination Type (Branch-Circuit Protective Device)
+type: radio
+options:
+ - Fusible switch + fuses
+ - Thermal-magnetic circuit breaker
+ - Motor circuit protector (MCP, instantaneous-only)
+default: Thermal-magnetic circuit breaker
+```
+
+## Reversing Starters {toc}
+
+### Reversing starters shall consist of two contactors with both a mechanical interlock and an electrical interlock to prevent simultaneous closure.
+
+### Reversing contactors shall have a mechanical interlock in addition to any electrical interlock, in accordance with NEC 430.84.
+
+### An electrical interlock alone is insufficient because a welded or mis-wired contact could energize both contactors simultaneously and short the supply. {note}
+
+### Reversing starters shall be furnished factory-assembled with the mechanical interlock installed; field-added interlocks are not acceptable.
+
+# Ratings and Sizing {toc}
+
+## Voltage Rating {toc}
+
+### The starter and all components shall be rated for the nominal system voltage of the served branch circuit.
+
+### The control power transformer (CPT) and contactor coil voltages shall be confirmed against the system voltage and the control source before ordering; a mismatch is a common cause of field rework. {note}
+
+```datasheet
+label: System Voltage
+type: radio
+options:
+ - 200 V, 3Φ
+ - 208 V, 3Φ
+ - 240 V, 3Φ
+ - 480 V, 3Φ
+ - 600 V, 3Φ
+ - 240 V, 1Φ
+default: 480 V, 3Φ
+```
+
+## NEMA Starter Size {toc}
+
+### NEMA-frame starters shall be sized by motor horsepower and supply voltage in accordance with the NEMA ICS 2 size table.
+
+### NEMA sizes and their maximum three-phase horsepower at 480 V are: Size 00 = 1.5 HP, Size 0 = 5 HP, Size 1 = 10 HP, Size 2 = 25 HP, Size 3 = 50 HP, Size 4 = 100 HP, Size 5 = 200 HP, Size 6 = 400 HP, Size 7 = 600 HP, and Size 8 = 900 HP. {note}
+
+### Size 1 (10 HP / 480 V) and Size 2 (25 HP / 480 V) cover the majority of commercial and light-industrial starters, with Size 1 the single most common item. {note}
+
+```datasheet
+label: NEMA Starter Size
+type: select
+options:
+ - Size 00 (up to 1.5 HP / 480 V)

+ - Size 2 (up to 25 HP / 480 V)
+ - Size 3 (up to 50 HP / 480 V)
+ - Size 4 (up to 100 HP / 480 V)
+ - Size 5 (up to 200 HP / 480 V)
+ - IEC frame (sized by motor FLA, not NEMA size)
+default: Size 1 (up to 10 HP / 480 V)
+```
+
+### IEC-frame controllers shall be selected by motor full-load current and utilization category (AC-3 for standard motor duty) rather than by NEMA size. {note}
+
+## Short-Circuit Current Rating (SCCR) {toc}
+
+### The listed SCCR of each combination assembly shall equal or exceed the available fault current at the starter line terminals as determined by the project short-circuit study.
+
+### A NEMA Size 1 fusible starter may carry an SCCR as low as 10 kA while the upstream panelboard delivers 42 kA or more; specifying a size without verifying SCCR against the available fault current is a frequent and serious error. {note}
+
+### The minimum specified SCCR shall be 42 kA RMS symmetrical at 480 V for general commercial and industrial applications; 65 kA or 100 kA shall be specified where the short-circuit study shows higher available fault current. {note}
+
+### Component SCCRs do not add; the assembly SCCR shall be established by a tested rating or a UL 508A series-combination calculation, never by summing individual device ratings. {note}
+
+```datasheet
+label: Minimum Short-Circuit Current Rating (SCCR) at 480 V
+type: radio
+options:
+ - 42 kA RMS sym (commercial/industrial baseline)
+ - 65 kA RMS sym
+ - 100 kA RMS sym (high available fault current)
+default: 42 kA RMS sym (commercial/industrial baseline)
+```
+
+### The available fault current at the starter line terminals shall be coordinated with the upstream distribution and the service, and verified against the [[sync/electrical-service-entrance]] short-circuit study.
+
+# Overcurrent and Overload Protection {toc}
+
+## Branch-Circuit Short-Circuit and Ground-Fault Protection {toc}
+
+### The branch-circuit overcurrent protective device shall be sized within the maximum percentages of motor full-load current established by NEC Table 430.52 for the device type used.
+
+### Per NEC Table 430.52, the maximum settings are: inverse-time (thermal-magnetic) breaker at 250% of motor FLC, instantaneous-trip (MCP) breaker at 800% (up to 1300% where required by NEC 430.52(C)(1) Exception), dual-element time-delay fuse at 175%, and non-time-delay fuse at 300%. {note}
+
+### High-efficiency motors frequently carry locked-rotor code letter G or H with elevated inrush, which can require the MCP or fuse to be set toward the upper end of the NEC 430.52 range; the locked-rotor code letter shall be coordinated with the mechanical engineer. {note}
+
+### Branch-circuit conductors shall be sized at not less than 125% of the motor full-load current in accordance with NEC 430.22.
+
+```datasheet
+label: Branch-Circuit Protective Device Type
+type: radio
+options:
+ - Inverse-time (thermal-magnetic) circuit breaker
+ - Instantaneous-trip (MCP) circuit breaker
+ - Dual-element time-delay fuse
+ - Non-time-delay fuse
+default: Inverse-time (thermal-magnetic) circuit breaker
+```
+
+## Overload Relay {toc}
+
+### A motor-overload relay shall be provided for running overload protection in accordance with NEC 430.32.
+
+### The overload relay shall have one pole per ungrounded conductor; three-phase motors shall be protected by a three-pole overload relay.
+
+### The overload relay shall be set from the motor nameplate full-load amperes (FLA) per NEC 430.6(A)(2), not from the NEC table FLC value; using the table value is one of the most common inspection failures. {note}
+
+### For motors with a service factor of 1.15 or greater or a marked temperature rise of 40°C or less, the overload relay shall be set at 115% of nameplate FLA per NEC 430.32.
+
+### For all other motors, the overload relay shall be set at 125% of nameplate FLA per NEC 430.32.
+
+### Electronic (solid-state) overload relays are preferred for high-cycle duty and for Class 20/30 adjustability, and provide field-adjustable trip via a front-mounted dial. {note}
+
+### Electronic overload relays with integral phase-loss protection shall be provided for critical three-phase motors, because bimetallic relays do not detect single-phasing until the surviving phases overload. {note}
+
+```datasheet
+label: Overload Relay Type
+type: radio
+options:
+ - Electronic (solid-state), adjustable
+ - Bimetallic thermal
+ - Manual motor protector integral trip
+default: Electronic (solid-state), adjustable
+```
+
+### The overload relay trip class shall be Class 20 for general-purpose motors, Class 10 for submersible pumps and motors with short thermal time constants, and Class 30 for high-inertia loads such as large fans and centrifuges.
+
+### Defaulting to Class 20 on a submersible pump motor (which needs Class 10) causes nuisance trips at startup, while Class 30 on a standard fan motor delays fault protection; the trip class shall be matched to the load. {note}
+
+```datasheet
+label: Overload Relay Trip Class
+type: radio
+options:
+ - Class 10 (submersible pumps, short thermal constant)
+ - Class 20 (standard / general-purpose)
+ - Class 30 (high-inertia loads)
+default: Class 20 (standard / general-purpose)
+```
+
+### For IEC-frame combination controllers, the short-circuit coordination type shall be declared on the submittal.
+
+### Type 2 coordination (no damage to the contactor or overload relay after a short-circuit test) shall be specified for process and other critical applications.
+
+### Type 1 coordination shall be permitted only for non-critical duty.
+
+```datasheet
+label: IEC Coordination Type
+type: radio
+options:
+ - Not applicable (NEMA frame)
+ - Type 1 (some damage permissible, non-critical)
+ - Type 2 (no damage, process/critical)
+default: Not applicable (NEMA frame)
+```
+
+# Disconnecting Means {toc}
+
+## Each combination starter shall include a disconnecting means rated for the motor in accordance with NEC 430.101 through 430.113.
+
+## The disconnecting means shall be capable of being locked in the open position with a provision that remains in place with or without the lock installed.
+
+## The enclosure door shall be mechanically interlocked with the disconnecting means so the door cannot be opened with the disconnect closed, except by a defeatable interlock for qualified persons.
+
+## A manual motor protector used as both disconnect and short-circuit protection shall satisfy the disconnecting-means requirements of NEC Article 430 for the motor it serves. {note}
+
+# Control Power and Accessories {toc}
+
+## Control Power {toc}
+
+### Control power shall be 120 V AC, 60 Hz derived from an integral control power transformer (CPT) unless an external control voltage is indicated.
+
+### The integral CPT shall be sized at not less than the inrush plus sealed VA of the connected control devices.
+
+### 500 VA is the typical default CPT size for a single starter with pilot devices. {note}
+
+### A control power transformer shall be furnished whenever control wiring extends beyond the equipment enclosure or a 120 V control circuit is required by the system integrator or BAS contractor.
+
+### Omitting the CPT from the initial pricing scope is a routine source of RFIs on projects with BAS or remote control requirements. {note}
+
+### The contactor coil voltage shall match the control power source.
+
+### A 24 V DC BAS output driving a 120 V AC coil without an interposing relay will damage the BAS output; this configuration shall not be applied.
+
+### Verify coil voltage compatibility before ordering; a coil voltage mismatch is a common source of equipment damage that is difficult to remedy in the field. {note}
+
+```datasheet
+label: Control Voltage
+type: radio
+options:
+ - 120 V AC via integral CPT
